I could not find anything related to fingerprint in the session you attached (comment #1).

The fingerprint/unlock job [1] runs the following python code:

  from evdev import UInput, ecodes as e
  ui = UInput()
  ui.write(e.EV_KEY, e.KEY_LEFTMETA, 1)
  ui.write(e.EV_KEY, e.KEY_L, 1)
  ui.write(e.EV_KEY, e.KEY_LEFTMETA, 0)
  ui.write(e.EV_KEY, e.KEY_L, 0)
  ui.syn()
  ui.close()

It simply triggers the keyboard shortcut to lock the screen (Super+L).

Unfortunately, this way of doing things does not work on Wayland. We need to update the code to find a way to lock the screen on Wayland.

Workaround: In the meantime, you can just lock the screen manually by pressing Super+L ("Super" = the Windows key).
